Reading Time: 2 minutesToday a new traing video has been added in the Backup Academy web site: “Basic principles of backup policies” by me :) In this lesson I will explain what is a backup policy and also give some information about the flow and the process to design a backup plan. Then I will detail some aspects of a backup policy, like What, Where and How. The purpose of this lesson is just give the bases of some concepts. For deep technical details on specific argument there are other lessons in the Backup Academy. Basic principles of […]

Reading Time: < 1 minuteIn the previous post we have discuss on how convert from VHD (used for example in Microsoft Hyper-V) to VMDK format (used in VMware products). Now let’s see how to convert from the other side. There are several tools to make this V2V operation:

Reading Time: < 1 minuteAs you probably already know a VM is incapsulated with a set of files that define VM properties and objects. Some of those files are the virtual disks files and each vendor use its own format: VMware use the VMDK and Microsoft & Citrix use the VHD format. Note that there could be more sub-types (for example for the VMDK files, but we will explain in future posts). To convert between different format you can use some kind of converter to perform a virtual to virtual (V2V) task.

Reading Time: 3 minutesAs most people know, Intel adopt a Tick Tock model for processors development: a tick advances manufacturing technology, a tock delivers new microarchitecture. Usually this mean that a tick means processors with more frequency speed (sometimes also more cores and/or more cache) and a tock means usually new features (but not necessary more frequency speed and/or more cache/cores). But when a new generation (tick or tock) as been introduced, after some months, this usually means cheaper processors (or at similar price) compared to previous generation. Now a possible confusion could be generated by the Westmere […]

Reading Time: < 1 minuteAfter a beta period, the Dell EqualLogic Host Integration Tools for Linux V1.1 has achieved (some days ago) Early Production Access status and is available for download via the standard Dell EqualLogic download site. Note that Early Production Access software is fully supported for production use. As a reminder, HIT/Linux includes tools that provide tight integration of EqualLogic PS Series arrays with Linux environments for enhanced protection, performance and simplified configuration and administration of EqualLogic PS Series storage arrays. HIT/Linux 1.1  feature enhancements over the previous release of HIT/Linux 1.0 include the following: Auto-Snapshot Manager/Linux […]

Reading Time: < 1 minuteAfter the acquisition of AppAssure, Dell today announced it has signed a definitive agreement to acquire SonicWALL, Inc., a leader in advanced network security and data protection. Now with the Force10 brand and the new (possible) Security brand, how will evolve the partship with Juniper (for the PowerConnect-J series)? Will finish as the one with EMC2?

Reading Time: 2 minutesThere are some cases, like for test and/or labs (but not only), where could be useful convert a local storage to a shared storage compatible with VMware vSphere (or other hypervisors). For local storage inside the host, the simplest solution is look for a virtual appliance that is designed for this scope (search for VSA – Virtual Storage Appliance). For a storage hosted on a Linux/Unix machine, probably the simplest solution is share the space with the NFS Server (of course it will be limited only to VMware vSphere). And when the storage is on […]
